New Relic Synthetics

New Relic Synthetics is a suite of automated, scriptable tools to monitor your websites, critical business transactions, and API endpoints. Ping monitors check that your site is up, while scripted browsers simulate real end-user activity. API tests let you ensure your backend is up too.

Synthetics uses a JavaScript-like scripting language to build advanced tests. Performance data and error screenshots let you see what went wrong when your site errors out, while integrated APM support connects Synthetics activity to transaction traces.

Synthetics monitors are available from data centers located around the world. You can even add your own private locations to monitor resources from inside your corporate firewall, or from new geographical areas.
